Description
Technical field
The present invention relates to electric-heating technology, and in particular to a kind of novel thick film heater.
Background technology
Stainless steel thick film heating body is main by stainless steel base, interior insulation dielectric layer, conductor layer, resistance heating from inside to outside
Layer and external insulation dielectric layer composition, current flow through from stainless steel inwall, wherein interior insulation thickness of dielectric layers in 100 microns,
Because the heat transfer from resistant heat generating layer to stainless steel base is apart from short, so thermal resistance very little, thermal response speed is fast.
Thick-film heating belongs to face heating, overall heated than more uniform, will not make because heater surfaces produce a large amount of bubbles
The efficiency of heating surface is reduced.Because heat can be conducted away in time, so whole heat-generating pipe surface temperature is not high, naked light will not be caused.
Security is good, and service life is long.
Due to thick-film heating element, operationally big multi-temperature is higher, causes its supply terminals to be connected with power cord connector
The soldering at place is easy to melting softening, and being pullled external force by power line due to power cord connector is influenceed to be easily separated from heating element heater power supply
Terminals, cause thick-film heating element cisco unity malfunction.
The content of the invention
For defect of the prior art, the present invention provides a kind of novel thick film heater, at thick-film heating element
When higher operating temperature, it is ensured that power connection is sustainedly and stably powered for thick-film heating element.
A kind of novel thick film heater, includes the thick-film heating element and shell of tubulose, the thick-film heating element peace
Put in the shell, it between the thick-film heating element and shell it is critical that be provided with elastic conductor piece, the elasticity
Conductor piece one end is fixed on the housing, and the other end of the elastic conductor piece suppresses the wiring in the thick-film heating element
On end.
More preferably to realize the utility model, it may further be, the elastic conductor piece includes tabletting head and fixed block, described
Tabletting head is integrally fixedly connected with fixed block by arc elastic conductor, and the fixed block is fixed on the housing, the tabletting
Head is suppressed on the terminals of the thick-film heating element；Power supply fast connecting terminal is provided with the fixed block, the power supply is fast
The fixed block integrally connected of connecting terminal and the elastic conductor piece；The power supply fast connecting terminal set on fixed block, is easy to wiring
And assembling, facilitate the utility model to be used with other matched with devices.
More preferably to realize the utility model, it may further be, the terminals of the tabletting head and the thick-film heating element
Fixed after suppressing contact by soldering；On the one hand make the terminal contact of tabletting head and thick-film heating element closer；The opposing party
Face, facilitates thick-film heating element and elastic conductor piece to be arranged in shell.
More preferably to realize the utility model, may further be, between the fixed block and the arc elastic conductor by
Strip conductor transition is connected；This structure makes the terminal contact of tabletting head and thick-film heating element more stable firm, it is to avoid because
Vibration produces the unstable influence of electric current.
It more preferably to realize the utility model, may further be, projecting point positioning hole and first be provided with the fixed block
Screw, the position that the fixed block is corresponded on the housing is provided with fixed platform, the fixed platform provided with projecting point and
Second screw, the projecting point passes through the projecting point positioning hole, and the second screw and the first screw correspondence is communicated.
The beneficial effects of the utility model：It is electrically connected with by the terminals of elastic conductor piece and thick-film heating element,
During thick-film heating element hot operation, the scolding tin melting softening even if between elastic conductor piece and thick-film heating element terminals
It is difficult for drop-off, even if scolding tin comes off, due to the resilient property of elastic conductor piece, make elastic conductor piece still with thick-film heating element
Terminal contact and electric connection；Elastic conductor piece uses bow-shaped structural, facilitates elastic conductor piece to be arranged on shell and thick film
Between heating element heater, and occupy little space.
